This is guaranteed to be unique while connected, but if you want to
track sessions over time isn't guaranteed to be. So, if you might have
pid=1234 now and also a month ago in a different session (especially if
you had a server reboot in-between).
Of course, if Riccardo doesn't need that, the pid is fine.
